The beijing great wheel takes 20 minutes to go around once. You enter a car at the loading platform for a 40 min ride. How far above the platform are you after 5 minutes? 10 min? 12.5 min? 23.66 min? At what time will you be 474 ft above the platform? Explain your reasoning. (r=316)

Question

OK, this seems to be a ferris wheel problem, but with a huge wheel....  And it does one revolution every 20 minutes.  So what does that tell you about how far you go per period of time?  Also, I think this need a diagram or more info for those questions.

e.mccormick · Answer

AH!  A radius ha sappeared.  hehe.

OK, so if the radius is 316.  That tells you a number of things about this, like the total height, which is the diameter.

correct...

e.mccormick · Answer

So at 10 minutes, which I marked, you woul be at the diameter, which is?  And yes, I know that is the easiest of those.  But this is about tracking how far a person has gone around a circle and equating that to height.

Is this for a trig class?  Because then you just ned to change the circle into a unit circle and use the trig ratios.

Yeah it is.

OK.  So lets look at it that way:|dw:1366323862333:dw|
